Radiative corrections with new heavy particles coupling to Higgs doublets destabilize the electroweak scale and require an ad-hoc counterterm cancelling the large loop contribution. If the mass scale m1 of these new particles in in the TeV range, this feature constitutes the "little fine-tuning problem". We consider the case that the new-physics spectrum has a little hierarchy with two...

A search for leptonic decays of Higgsino-like neutralinos in the case of a compressed mass spectrum using a track, a reconstructed lepton and missing transverse momentum is presented. We consider the case of a second-lightest neutralino decaying into a dark matter candidate - lightest neutralino - and two leptons via an off-shell Z boson. In the case of a very small mass differences between...

The measurements of the muon and electron anomalous magnetic moments hint at
physics beyond the standard model. We explain why asymptotically safe
extensions based on an enlarged scalar sector and Yukawa couplings between
leptons and new vector-like fermions explain the data naturally. Models
stabilize the Higgs potential, predict the tau anomalous magnetic moment,
and feature new...

This presentation is a potpourri of Aachen results searching for BSM. One key search looks for excited leptons (e* and mu*) in the contact interaction channel providing the maximum sensitivity in terms of lstar mass. To put it in context, its sensitivity in terms of mass and compositeness scale Lambda is compared with the llg channel. We also search for new heavy charged boson, W', in the...

The lack of evidence of New Physics coming from direct searches of resonances at the LHC calls for an increase in efforts to devise new observables that can indirectly probe New Physics. If new resonances exist but are out of the reach of the LHC or future colliders, they could manifest themselves through a harder p_T spectra with respect to the SM. In this context, the diboson final state has...

We study a scale-invariant minimal supersymmetric Standard Model which allows for an implementation of inflation in the early universe. This model has the same field content as the Next-to-Minimal Supersymmetric Standard Model (NMSSM) thus can be distinguished by observations in the scalar sectors. A crucial role play the singlet components. We point out that there might exist light...

The current status of a search for supersymmetry (SUSY) in events with same-flavor opposite-sign lepton pairs is presented. The analysis utilizes data recorded by the CMS detector from 2016 to 2018. As the considered signals include strong production of SUSY particles, jets are also required, along with large missing transverse momentum, which arises from undetected LSPs. An important feature...

The lighter chargino (chi1) is a prime candidate to be the
next-to-lightest SUSY particle (the NLSP). Several analyses have been
done of chi1 pair-production at the ILC, at specific model-points,
showing that detection and property-determination is possible, even for
very difficult cases. However, no recent studies have evaluated the
reach of the ILC to detect chi1 pair production in...
